HONEYCOMB CERAMIC STRUCTURE

摘要

PURPOSE:To obtain a honeycomb ceramic structure having high thermal shock resistance, capable of being constituted in any dimension and in a large size by laminating honeycomb ceramic modules of a fixed shape in the axial direction of their open cells. CONSTITUTION:This honeycomb ceramic structure 1 is constituted by laminating plural honeycomb ceramic modules 2 (cell walls 4) having fixed open cells 3 and fixed thickness in the axial direction of the open cells 3. The honeycomb ceramic modules 2 are generally a laminar or disklike shape. The honeycomb ceramic modules 2 have preferably >=10cm longer diameter L in the cross direction of the open cells 3, >=1mm thickness T in the axial direction of the open cells 3 and <=0.5T/L. A layer material for shock absorption having open cells is preferably arranged between the honeycomb ceramic modules 2 and/or the end face of the honeycomb ceramic structure 1 so as to absorb at least one of mechanical and/or thermal stress.
